Symmetricom Launches Small Cell Clocks for Use in LTE Networks

Symmetricom has launched a new portfolio of Edge Master Clocks specifically designed to support small cell deployments for 3G and LTE networks.

"The advent of small cells in the mobile network increases the
complexity of synchronization. Small cells need to be synchronized within the
tight tolerances of precision defined by the standards and required for delivery
of end user services," said Jennifer Pigg, vice president, Yankee Group.
"Moving master clock capability to the edge will help satisfy several
requirements that mobile operators tell us are critical for improving service
delivery and performance at the edge of the network where bandwidth is needed
the most."

The TimeProvider 2700 and 2300 Edge Master Clocks are IEEE 1588 (PTP)
synchronization solutions designed to meet the deployment requirements for small
cells in current networks by locating a grandmaster at or near the edge, or by
overlaying the network with advanced boundary clocks at specific locations.

They enable carrier networks to support LTE-TDD and LTE-A stringent
requirements for frequency and phase synchronization without having to replace
existing equipment in the backhaul network. In frequency synchronized networks (LTE-FDD,
as well as 2G/3G), Edge Master Clocks can be deployed to eliminate timing issues
caused by the backhaul network and high packet delay (PDV) environments inherent
in Carrier Ethernet networks.

Multi-sync capability ensures service continuity in the event of loss of one
or more of the primary sync signals or the GNSS signal is compromised. The
solution is also optimized for deployment in small to large networks with
license options supporting between 8 and 64 base stations and/or small cells,
allowing for network scalability.
